Severe Weather Coordination Message #2 – Monday 7/18/22 Severe Weather Potential

Hello to all…

..Isolated to Scattered Strong to Severe Thunderstorms are likely across Western Massachusetts and Northwest Connecticut and possible through Northeast Connecticut, Northwest Rhode Island and Central and interior Northeast Massachusetts along and northwest of the I-95 corridor Monday Afternoon and Evening with strong to damaging winds, hail, frequent lightning and heavy rainfall with urban and poor drainage flooding as the main threats and an isolated tornado as a secondary threat.
..The Storm Prediction Center (SPC) has placed portions of Western Massachusetts and Northwest Connecticut in a slight risk of severe weather with a marginal risk for severe weather from the I-95 corridor of Boston to Providence north and west through Central and Northeast Massachusetts and Northeast Connecticut..
..SKYWARN Self-Activation will monitor the severe weather potential for Monday Afternoon and Evening..

An area of showers and thunderstorms is moving through the region Monday Morning. The area is mostly showers across interior Southern New England with some strong thunderstorms across South Coasal Connecticut and over Long Island Sound. The activity over Long Island sound will be monitored for an isolated strong to severe thunderstorm over Southeast New England but this area should largely be non-severe and should clear Western and Central Massachusetts and Western and Central Connecticut between 12-2 PM and areas further east around or after 2 PM. After that area moves through, the potential for isolated to scattered strong to severe thunderstorms will be likely in the Slight Risk for severe weather area and possible in the marginal risk for severe weather area for Monday Afternoon and evening. The headlines depict the current thinking. Key factors include:

1.) Amount of heating and destabilization that can occur after the initial showers and thunderstorms move through the area. As of 1030 AM Monday Morning, satellite imagery is showing a lot of clouds but some thinning occurring in Central Pennsylvania and Central New York. This clearing if it becomes more widespread coupled with the very strong shear profiles would set the stage for strong to severe thunderstorm development later this afternoon into early evening. Also, given the strong wind shear, it will not take much heating given the high dewpoint air in the region to allow for isolated to scattered strong to severe thunderstorm development particularly in the slight risk area. The key will be having at least some cloud breaks and the movement of the current rain area east of the slight and marginal risk areas by roughly the 12-2 PM time window and that the warm front gets far enough to the north to allow a good portion of the risk areas to be in the warm sector.
2.) The timing of the cold front and how far east the forcing gets to allow for thunderstorm and severe weather development.
3.) Heavy rainfall is expected. The rain will be beneficial but if its heavy enough and falls in a short enough period of time, it can result in urban and poor drainage flooding in susceptible areas.

SKYWARN Self-Activation will monitor the severe weather potential for Monday Afternoon and evening. This will be the last coordination message as we shift into operations mode.

Severe Weather Coordination Message #1 – Monday 7/18/22 Severe Weather/Flood Potential

Hello to all…

..Isolated to Scattered Strong to Severe Thunderstorms are possible across portions of Western Massachusetts and Northern Connecticut Monday Afternoon and Evening with strong to damaging winds, hail, frequent lightning and heavy rainfall with urban and poor drainage flooding as the main threats and an isolated tornado as a secondary threat. The Storm Prediction Center (SPC) has placed portions of Western Massachusetts and Northwest Connecticut in a marginal risk of severe weather for Monday and the Weather Prediction Center (WPC) has placed much of Southern New England north and west of the I-95 corridor in a marginal risk for excessive rainfall..
..SKYWARN Self-Activation will monitor the severe weather potential for Monday Afternoon and Evening..

An area of showers and thunderstorms will likely form and move into the region during Monday Morning. This area should be non-severe but will be monitored for any severe potential. After that area moves through, the potential for isolated to scattered strong to severe thunderstorms will be possible for Monday Afternoon and evening. The headlines depict the current thinking. Key factors include:

1.) Amount of heating and destabilization that can occur after the initial showers and thunderstorms move through the area presuming that forms as expected.
2.) The timing of the cold front and how far east the forcing gets to allow for thunderstorm and severe weather development.
3.) Heavy rainfall is expected. The rain will be beneficial but if its heavy enough and falls in a short enough period of time, it can result in urban and poor drainage flooding in susceptible areas.

SKYWARN Self-Activation will monitor the severe weather potential for Monday Afternoon and evening. Another coordination message will be posted by 1230 PM Monday Afternoon.

Severe Weather Coordination Message #1 – Thursday Afternoon and Evening 7/14/22 Severe Weather Potential

Hello to all…

..After the most organized severe weather event so far in this quite summer season of severe weather on Tuesday 7/12/22, isolated strong to severe thunderstorms are possible in Eastern Massachusetts and Rhode Island this Thursday mid-afternoon to early evening particularly along any seabreeze boundaries that form in and around the marginal risk area. Strong to damaging winds, hail, frequent lightning and localized heavy rainfall leading to brief urban and poor drainage flooding are the main threats..
..The Storm Prediction Center (SPC) has placed much of Eastern Massachusetts in a marginal risk for severe weather this Thursday Afternoon and Evening..
..SKYWARN Self-Activation will monitor any isolated strong to severe thunderstorm potential for this Thursday Afternoon and Evening..

Tuesday 7/12/22 featured the most organized severe thunderstorm event in what has been a quiet summer season of severe weather for Southern New England. Any post storm damage reports, pictures and videos can be posted on our WX1BOX social media feeds, as a reply to this message or to the email address pics@nsradio.org. Below is the NWS Local Storm Report and Amateur Radio log from the Tuesday 7/12/22 severe weather event:

WX1BOX Amateur Radio Complete log:
https://wx1box.org/wp-content/uploads/2022/07/reports_7_12_22.pdf

For today, we are not expecting an organized severe weather event like Tuesday 7/12/22 but strong instability with some strong upper level winds aloft along with a trigger via seabreeze fronts/boundaries could allow for isolated strong to severe thunderstorms in Eastern Massachusetts and Rhode Island and SPC has upgraded much of Eastern Massachusetts to a marginal risk for severe weather. SKYWARN Self-Activation will monitor this potential for this Thursday Afternoon and Evening.

Severe Weather Coordination Message #2 – Tuesday Afternoon and Evening 7/12/22 Severe Weather Potential

Hello to all…

..Isolated to Scattered Strong to Severe Thunderstorms are possible across interior Southern New England Tuesday Afternoon and Evening. Strong to damaging winds, hail, frequent lightning and heavy rainfall leading to urban and poor drainage flooding are the primary threats. Timeframe would be any time between 3-10 PM Tuesday.
..The Storm Prediction Center (SPC) has expanded the slight risk for severe weather area into Western and Central Massachusetts and into Northwest and North Central Connecticut from roughly Tyngsboro, through Worcester Massachusetts and Vernon, Connecticut west with a marginal risk for severe weather east of the Tyngsboro-Worcester-Vernon line to the Boston to Providence I-95 corridor of Eastern Massachusetts and Northwest Rhode Island..
..SKYWARN Self-Activation will monitor the severe weather potential for Tuesday Afternoon and Evening..

Heat and humidity will build into the region on Tuesday ahead of a cold front that will sweep through Southern New England Tuesday Afternoon and Evening. The headlines depict the current thinking which expands the highest severe weather potential into portions of North-Central Connecticut and Central Massachusetts. Key factors for the severe weather potential Tuesday remain:

1.) Amount of heating and destabilization ahead of any late Tuesday morning/early afternoon convection that may impact parts of the region.
2.) Amount of moisture that returns after any morning convection. Models show drying in the atmosphere during the afternoon with some moisture return towards late Tuesday Afternoon and Evening. If this moisture return can occur not too far past the time of peak heating, it will increase the severe weather potential. If the moisture return is too late, severe weather potential will be reduced with most thunderstorms being non-severe in nature later Tuesday Evening.
3.) Amount of forcing with the front and how quickly it moves in for the front to tap into sufficient wind shear profiles and expected moderate instability levels.

SKYWARN Self-Activation will monitor the severe weather potential for Tuesday Afternoon and Evening. This will be the last coordination message as we shift into operations mode. Below is the NWS Boston/Norton Area Forecast Discussion, Hazardous Weather Outlook and SPC Day-1 Convective Outlook:

Severe Weather Coordination Message #3 – Saturday Afternoon & Evening 7/2/22 Severe Weather Potential

Hello to all…

..Isolated to scattered strong to severe thunderstorms remain likely Saturday Afternoon and Evening across much of Southern New England with strong to damaging winds, hail, frequent lightning and heavy rainfall leading to potential urban and poor drainage flooding as the main threats. The Storm Prediction Center (SPC) has continued much of Southern New England in a Slight Risk for severe weather except for Southeast Coastal Massachusetts and Newport County Rhode Island which are under a marginal risk for severe weather for Saturday. Timeframe is between 2-8 PM give or take 1-2 hours..
..SKYWARN Self-Activation is likely Saturday Afternoon and Evening to monitor this severe weather potential..

Overnight, clusters of strong and a couple isolated severe thunderstorms occurred in the region overnight and were still ongoing in Southeast New England with an area of showers across Southeast New York, Northern Connecticut and into Northwest and North-Central Massachusetts. This area will move through during the late morning and early afternoon hours and behind it will be some clearing and destabilization that will set the stage for a potentially active severe weather day that remains likely on Saturday Afternoon and Evening with the potential for isolated to scattered strong to severe thunderstorms in clusters or line segments to affected much of Southern New England Saturday Afternoon and Evening. There has been little change to the ongoing forecast based on the current model runs.

As is the case with strong to severe thunderstorms, not every location, city or town will see this activity but isolated to scattered pockets of strong to severe thunderstorms will affect the region as a cold front brings an end to intense heat and humidity to the region. Conditions will dry out late Saturday Night into Sunday Morning from northwest to southeast allowing for nice summer weather for July 4th long weekend activities from Sunday Afternoon through Monday Evening. The headlines depict the current thinking. Key factors remain:

1.) There continues to be some shower and thunderstorm activity this Saturday Morning which should clear out from the area in the late morning and early afternoon hours per radar and satellite imagery. The amount of clearing to allow for more intense destabilization after this activity moves through will be a key factor in determining the extent of strong to severe thunderstorms during the time of peak heating Saturday Afternoon and Evening.
2.) If there is strong clearing with the favorable wind shear profiles in place, this could allow for more a potent severe weather event across the region and this will be monitored.

SKYWARN Self-Activation is likely Saturday Afternoon and Evening to monitor this severe weather potential. This will be the last coordination message as we shift further into operations mode as we have been active during the overnight and early morning period.
